RAYMOND To all whom it 'may concern:

Be it known that I, RAYMOND H. BAN- NING, a citizen of the United States, residing in the city and `county of San Francisco and State of California, have invented certain new and useful Improvements in Screen Attachments for Vindow-Sashes, of which the following is a specification.

The hereinafter' described invention relates to the attachment of a screen to the of windows in such a manner that the screen will extend and contract with the lowering and raising of the sash, whereby with the lowering of the said sash wholly or partially the opening which otherwise exists at the head thereof is screened to prevent insects entering the rooin; the roll carrying attached thereto the `weight for the upper sash for giving a. perfect balance thereto, whereby the window `frame or casing may be constructed without having thensual pulleys fitted therein to receive the weight cords for the upper sash,`inasmuch as the sash cords are transferred from the upper sash to reels The objects of the invention are to simplify the attachment of screens to theupper sash of the window; to remove therefrom the direct connection thereto of the. cords for the suspended sash weights; to provide for aperfect balance of the sash and screen attachment; to dispense with the employmentof the pulleys in the window frame for the weights for the upper sash and by so doing saving in the cost of such pulleys and the expense incident to the proper placing of the same; to provide for the quick attachment anddetachinent ofthe screen relative to the upper sash of the window.; and to provide a screen attachment fully protected and hidden from view, infact, housed within the windowcasing, and of such a characi ter as to be readily applied to the. upper sashes of windows at present in use at a small expense. i

1With these objects in view the invention comprises the combination ofl the working elements or parts and the details of construction hereinafter fully described and pointed out, reference being had to the accompanying drawings for a comprehension thereof, wherein-- Figure 1 is a broken elevation disclosing the position of the screen mechanism relative to the window casing or frame, the con- Specifieation of Letters Patent.

SCREEN ATTACHMENT FOR WINDOW-SASHES.

nection between the free end of the screen and the upper sash of the window, and the `manner of suspending the balance weights for the said sash and the screen attachment. Fig. 2 is a perspective view of the angleplate for uniting the F ign?)` is a detail view disclosing the ratchet and pawl for holding the weight reels locked against movement` when the screen is detached from the upper y sashl Fig. 4 `is a detail view of the supporting axles for the reels of the sash cords for the suspended weights. Fig. 5 1s a view in Ielevation of one of the end plates, disclosj ing the opening for receiving the end of the journal.

In the drawings, the numeral 1 is used to designate the upper sliding sash of an ordithe same working within the To the top iail 3 angle-iron or attach- The angle-iron t is provided with `a series of slots (i, through which extend the lock-catches 7, slidably rail 3 by means of the securl/Vhen the `lock-catches 7 are turned to overlap the angle-iron 41, the saine is held `to the top-rail 3.' `The screen 5 exfroin a roll 9 constructed of suitable material, which roll is situated within `a pocket 1() in the head 11 of the frame or `casing 2, and the aid roll is provided with the socket pieces 1 2 and the ends thereof. The screen `roll 9 is held inplace by means of the axles `or journals 13 and 13', the reduced square end 14 of the journal 13 and 14.- of the jonr- :nal 13 fitting within the respective socketand 12', while the body portionzof the said journals extends through bearings fin the window jambs 15 and 15` and extend respectively within the reels 1G and 1G', to Lwhichthey are united by tap screws 17. j

The journal 13 is held inwardly pressed by means of the tension spring 17which hears against the window jamb 15 and a collar 18 on the said journal adjacent its reduced end 14, the tension or pressure of the spring 17 serving to hold the roll 9 in adjusted position relative to the journal 13. The said journal 13, adjacent its reduced end is formed or l iovided with a fixed ratchet wheel 1S, which when it is desired to to unwindthe screen,

hold the screen roll locked against rotation is engaged by a pawl 18 pivoted to the plate 19 secured to the inner face of the window jamb 15.

To the reels 16 and 16 the sash cords 20 and 20 are attached in any suitable manner, to which cords are united the sash weights 21 and 21 suspended thereby within the weight pockets of the window frame or casing and the said weights are held in proper position by means of the guide rolls 22 over which the sash cords work, said rolls being carried by the brackets 22 secured within the weight pockets.

Access may be had to the overhead pocket 10 within which the screen roll 9 is situated by means of the removable bottom piece 23 of the casing' or frame head 11, the said bottom piece 23 being slidably fitted in place.

In securing the roll 9 with the screen thereon in position within the pocket 10 the end carrying the socket piece 12 is iirst itted onto the journal or axle 13 and forced endwise to depress the spring 17 and nuove inwardly the journal 13 to place the opposite end of the roll in alinement with the free end of the journal or axle 13 which is held against end movement by means of the ratchet 18 thereon, when the socket piece 12 is Vplacedy onto the squared end of the said journal or axle 13 by releasing the inward end pressure on the' roll 9, the same being `forced into place by the pressure 0i" the spring 17. The angle-iron or attachment plate 4, to which the free end of the screen 5 is united is then secured to the top rail of the upper sash 1 by or bolts 7 extended through the slotted por-y tions G of the said angle-iron 4L or until the said catches or bolts overlap the same.

Vith the parts assembled as above stated, as the upper sash of the window is lowered and raised the screen is unrolled lfrom the roll 9 and wound thereon, due to the fact that as the sash is lowered the roll is rotated while on the sash being raised the suspended weights come into play and impart an opposite rotation to the said roll for the winding of the screen thereon, the weights lowering within the weight pockets and the unwinding of the weight cords from the reels 16 and 16 causing rotation oi the roll 9 held to the journals or axles y thereof. The expansion and contraction of the screen is thus proportioned to the turning `the lock catches ing` held endwise under `with the squared portion thereof seated within one of said squared receiving pormovement of the upper sliding sash, so no matter in what lowered position the sash stands, the space between the. top rail thereof and the bottom of the casing head is always protected against the entrance of insects into the room by reason of the screen 5 covering said opening.

In case it is desired to remove the upper sash or disconnect the same from the screen for any purpose whatsoever, it is only required to lower the window sash and turn the lock catches or bolts 7 to stand in alinenient with the slots 6 of the angle-iron or attaching strip t, when the said strip mayy be lifted clear of the top rail of the sash. However7 prior to releasing the angle-iron or strip t, the pawl 18 pivoted to the fixed plate 19 is thrown into engagement with the ratchet wheel 18 to hold the roll 9 locked against rotation and thereby maintain the weights in adjusted position.

I am aware that the detailed parts herein shown and described may be varied as to construction, and I do not wish to be understood as restricting the invention to such details of construction.

Having thus described the invention what I claim as new and desire to secure by Letters Patent is- In an attachment for the described purpose, the combination with end sockets secured to the ends thereof 'and provided with squared receiving portions `i'ormed therein, journals provided on their a screen roller,

inner ends with squared portions adapted to be inserted in said receiving vportion for mounting the roller, one of said journals betions, and the other of said journals provided with a shoulder to prevent the longitudinal movement thereof, and the squared portion of said journal being received within the other of said squared receiving portions, a reel for a sash weight cord detachably connected tothe outer end of each journal, and a screen secured to the screen roller.

In testimony whereof I have signed my `naine toV this specification in the presence of Itwo subscribing witnesses.
